Coronavirus - is low vitamin D a factor - vitamin D and respiratory conditions

[AlfredoLong]

The benefit of vitamin d supplements for those with deficiencies is huge, but the benefit to those without a deficiency are still quite significant, sitting at around a 20% reduction in respiratory infections. I'd take a 20% less chance of complications with COVID19 for no downside.

[ElishaHunt]

I've used Vit D3 plus k2 cause I was Vitamin D deficience. However, there are evidence that Vitamin D Supplementation could reduce risk of Influenza and COVID-19 Infections and deaths.

I take 5,000 iu Vitamin D3 from vitaminexpress, one per day. Feel much more balanced. I actually take it before bed and I feel like I wake up more refreshed when I do.

1 in 4 COVID patients hospitalized while vitamin D deficient die – Israeli study

"Results Of 1176 patients admitted, 253 had VitD levels prior to COVID-19 infection. Compared with mildly or moderately diseased patients, those with severe or critical COVID-19 disease were more likely to have pre-infection vitamin D deficiency of less than 20 ng/mL (OR=14.30, 95%, 4.01-50.9; p < .001); be older (OR=1.039 for each year, 95% CI for OR, 1.017-1.061; p< .01), and have diabetes (OR=2.031, 95% CI for OR, 1.04-3.36; p= 0.038). Vitamin D deficiency was associated with higher rates of mortality (p<0.001) and comorbidities including COPD (p=0.006), diabetes (p=0.026), and hypertension (p=0.016)." https://www.medrxiv.org/content/10.1....04.21258358v1

Vitamin D deficiency is associated with higher hospitalisation risk from COVID-19: a retrospective case-control study

https://academic.oup.com/jcem/advanc...gab439/6303537

CONCLUSIONS
Vitamin D deficiency is associated with higher risk of COVID-19 hospitalisation. Widespread measurement of serum 25(OH)D and treating any unmasked insufficiency or deficiency through testing may reduce this risk.
